A rllhe invention relatesto forms for poured building. walls and has for one of-its objects the provision i of a ysim-ple construction i ofY form which provides for reinforcingrbridge f members between .the` spaced outerr and` inner w-alfll sectionspof-g the poured wallL and which may bejreadi-lyI assembledand after the pouring of: tlieLwa-ll,I disassembled and withdrawn sothatf-it may be used again. Another object is the provision of' a form oompris'i'ngf` spaced side sections. and endfsec-` tions ,movable transversely oi and between the? side-sections, the'seetions having cooper-l ating bearing surfaces which-permit. the sidef H sections tomoveftoward eachother when the end sections*y have` been moved transverselyinward' relativeto; theY side sections.; Further objects of the invention' reside in the novel: features of;V construction and:v combinationsV and' arrangements i of partST as more' fully hereinafter s'et'forth.` v In'tliedrawings: Y I Figurer-is aperspective-view of a portion of a building in the course of construction and? showing aform 'embodying my invention; f

adjacent end sections 6 and 7 of the inner form as well as between the adjacent flanges E20 oi" the outer vertically extending angle bars 17. rl`he bar 19 has the struck-out tongues S21 intermediate its ends for-engag-v ing the sides of the end section 7, the adjacent end section 6 being positioned by means of the hook 22 pivoted upon the end section 7 and detaehably engaging the pin 23 upon the end section 6. 24 is a U-shaped clip having the transversely extending projection 25 upon one of its legs for engaging in registering openings in the adjacent flanges 20 of the angle bar 17 and in the bar 19 to position the side members of the outer form relative to the side sections of the inner form and also to align the sides of the outer form with each other. The other leg of the clip 24 is longitudinally slotted at 26 to form bifurcations engageable on opposite sides of the adjacent flanges 20 of the angle bars 17 to hold the adjacent side members of the outer form together.

With this arrangement, itl will be readily seen that I have provided a simple construction of form for building walls in which the side sections and side members are detachably held in correct position relative to each other and may be readily assembled and disassembled, It will also be seen that with my arrangement the end sections uponthe transverse movement relative to the side sections of the inner form will permit of movement of the side sections toward each other and also that these end sections serve to position the side sections of the inner form relative to the side sections of the outer form. A further feature resides in the arrangement of transverse bar and clips at the ends of this bar for holding the side sections and members of the form in their correct rela-- tive positions, the arrangement of bar and clips being such that they may be formed of stampings at a comparatively low cost.

That I claim as my invention is:

' l. In a poured wall form, the combination with spaced side sections, of end sections movable between said side sections, each end section being provided with inclined transverse recesses in one of its faces.

2. Ina form for a poured wall having spaced inner and outer wall sections and integral diagonal bridge members therebetween, the combination with spaced side sections, of end sections movable between said side sections, said end sections having transverse diagonally extending recesses in their outer faces and adjacent end sections having their recesses registering to form the diagonal bridge members for the wall.

3. In a poured wall form, the combination with spaced side sections, of end sections slidably movable inward of and be- -tween said side sections, said sections having braces normally maintaining the spaced relation of the side members and arranged to permit of the movement of said side scctions toward each other upon the transverse movement of said end sections inwardly relative to said side sections.

4. In a poured wall form, the combination with spaced side sections, of end sections movable inward of and between said side sections, said end sections being provided with diagonal recesses in their outer faces, and tapering outwardly to permit of the movement of said side sections to each other whensaid end sections have been moved transversely inward.

5. In a poured wall form, the combination with spaced side sections comprising plates having inturned edges, of outwardly tapered end sections movable between said side sections, each end section having inclined recesses in its outer face. j

6. In a. poured wall form, the combination with spaced side sections, of end sections provided with inclined recesses extending transversely thereof.

7. In a form for a poured wall having spaced inner and outer wall sections and diagonal integral bridge members therebetween, the combination with spaced side sections, of end sections having transverse diagonally extending recesses in 'their outer faces and adjacent end sections having their recesses registering to form the diagonal bridge members for the said inner and outer wall sections.

8. In a poured `wall form, the combination with spaced side sections, of end sections projecting beyond said side sections and provided with recesses extending transversely thereof, adjacent end sections of successive forms registering and hooks engaging said end sections for maintaining alignment of said forms.

9. Means for pou-ring a hollow wall comprising an outer form and an innerform, a plurality of longitudinally aligned side members included in said outer form and a plurality of longitudinally aligned side sections included in said inner form,` a onepiece bar extending transversely of the meeting portions of adjacent longitudinally pairs of outer and inner forms, and means cooperating with said bar for holding the successive longitudinally adjacent pairs of outer and inner forms in aligned relation.

10. A form for a poured wall having spaced inner and outer wall sections and diagonal integral bridge members therebetween,said form having spaced side sections, and means for forming said diagonal integral bridge members between the wall sections.

11. In a form, the combination with inner and outer molds, the latter including a pluralityv of side members having adjacent anges at their edges, of a bar extending transversely of said side members and between said flanges, means on said bar for po-V sitioning said inner mold and a U-shaped clip having one leg thereof formed lWith a bifurcated portion adapted to receive said flanges and the other leg thereof adapted to be extended through aligned openings in said flanges and bar. v

12. In a form, the combination with inner and outer molds, the latter including a plu- `rality of side members having adjacent flanges at their edges, of a bar extending transversely of said side members and between said flanges, said bar having tongues struck out therefrom for locating said inner mold, and a clip formedV at one end With a bifurcated portion for embracing said flanges, and at the other end with another portion adapted to be extended through said flanges and bar.

In testimony whereof I aliX mysignature.
